	Whether the data generated by this DI should be published to GPU emitters in other Niagara systems.
bool	bUpdateDestinationDataEveryTick
	Whether this DI should request updated destination data from the Data Channel each tick. Some Data Channels have multiple separate data elements for things such as spacial subdivision. Each DI will request the correct one for it's owning system instance from the data channel. Depending on the data channel this could be an expensive search so we should avoid doing this every tick if possible.
